Cool! Thanks for the footage!
Tips ... well ... it has probably been said/written before, but try to work on sweeps, don't stay on your back, try to get top position, role with your opponent if he tries to evade an armbar or something else, be more aggressive ... you seem to be holding on a more passive form ... try more stuff, if one thing doesn't work, quickly switch to something else (e.g. if armbar doesn't work, go for a triangle choke or leg, ... and vica versa) ... work on instinct, try not to think "urhm ... maybe if I ... damn ... how did that move work was in class? ... "
It is not a bad thing to lose, if you want results, you got to keep up the good work (roll alot, try alot, learn from others, work with people better than you, go 100%) ...
